"Containers are a popular method of distributing and running software. Like all packaging technologies, containers need to be maintained.

Since containers bundle their dependencies, there will be occasions where it is necessary to mass rebuild all of the containers that Fedora distributes. This mass rebuild introduces quite a few challenges for Fedora's infrastrucutre systems, from OpenShift Build System to Bodhi to the container registry. For example, layered images reference containers in the stable tags, so how can Bodhi push out layered image updates if the new base layer hasn't been stabilized yet? How do we ensure that updates that depend on other updates work?

This talk will present the many challenges that Fedora faces as well as the solutions that are underway."
